Add examples

[megoth]

Work is currently being done on the shapes for WebID Profiles, and in this regard it's useful to have some examples to compare against.

I propose at least two examples:

1. Minimal: No optional fields, only required fields with the least complex values used
2. Maximum: All optional fields used, with all shapes of values used

In addition, it might be useful to have some variants that cover some alternative shapes for values (if applicable - I don't have a complete overview of what a profile might contain).

I've realized that I'm not able to prioritize this task anytime soon, so I'm posting this in hope that someone else have the time and knowledge to take this task on. If not, I'll try to get to this in the future, but no promises on when.
